Symptoms of Motion Sickness

After age 12, the main symptom is nausea (feeling sick to the stomach).

Causes of Motion Sickness

Symptoms are mainly triggered by motion. Sea sickness or amusement park sickness are the most common types. Fun-park rides that spin or whirl are some of the main causes. The Tilt-a-whirl is a good example of a ride to avoid. Also seen during travel by train, aircraft and even car.

The cause is a sensitive center in the inner ear. This center helps to maintain balance.

As a car passenger driving on winding roads, 25% of people will have symptoms. Under extreme conditions (e.g., high seas) over 90% of people have symptoms.

Strongly genetic: If one parent has it, 50% of the children will have it.

It is not related to emotional problems. The child cannot control it with will power.
